Powder metallurgy is a technology designed to maintain a small carbide size. Read about my tests in this article. You can read an article I wrote on budget steels here. Both steels are popular among knife manufacturers and both have their strengths and weaknesses. What about K390? -> Maybe prequenched 14c28n could be a little tougher than AEB-L? Type 8Cr, the more common formulation, is worse than AUS-8: a little more prone to corrosion and not quite as hard. 14C28N steel is known to offer among the best if not the best toughness in knife steels out there. It isnt impossible, but contrast may not be very good and the austenitizing temperatures of the two steels arent very compatible. Anyway, astute comment, but edge retention does mean a lot in woodworking. You said wood is not a particularly abrasive material and in absolute terms that is very true. Or is this an argument that tends to be rooted more in the presumption that Japanese steel > Chinese steel than any practical difference in reality?
14c28n Steel Is Good for Knife? Here's The Best Review For - Milkwood MagnaCut has the lowest chromium of any of the below steels but all of its chromium is in solution (no chromium carbide) and the fact that it has no chromium carbide also gives it the maximum level of corrosion resistance for a given amount of chromium. There is no such thing as a steel that is a 10 in both toughness and edge retention. I did a large study of different knives with identical sharpening and edge geometry. Among Vancron SuperClean, Agomi #1 and Shirogami #1, Which one tends to have finer grain size and Sharper edge? Even metallurgists can have a difficult time estimating properties just based on the elements. drop point Recommendations are welcome, If you are cutting against metal I would maybe try K390 in a Spyderco or an S110V knife if you need stainless. So hard vanadium carbides means you get more edge retention for a given amount of carbide. It was originally developed for use as ball-bearing steel by NASA. These properties make steel a good choice for making kitchen, fishing, and everyday knives. I was thinking maybe Sleipner or A2 would be best if a PM steel was out. A cryo treatment and close temperature control is necessary to achieve those hardness levels. Its a costly and challenging process, but it makes extremely fine-grained steels, some of the best for knives, and makes some processes that were previously impossible a reality. Obviously Ill let you check the manuscript prior to publication. I have a question about the chart Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. Question. 14C28N is a stainless steel that was developed specifically for use in knives. 0.62% of Carbon: Makes knives harder and more resistant. Also many hardwoods will dull planer blades just because theyre more dense. The very good toughness of MagnaCut meant that it didnt chip despite this relatively high hardness and the difficulty of the test. These steels are best for knives that dont see impacts and are some of the most difficult to sharpen. And Ive done a lot of experimental work on knife steels where I feel more confident in my own ratings. D2 is a high carbon, high chromium die steel and is the highest carbon alloy tool and die steel typically used in knife making. Below shows Vanax tempered at 400F on the left and 1000F on the right after 1% saltwater for 24 hours: There are many other ways in which knife steel performance can be reduced through heat treatment but I cant cover them all in this article so hopefully these illustrative examples will be enough. Not as tough as the best carbon steels, it's tougher than most . S45VN Another common heat treating choice that is not even categorized as a mistake is tempering in the high temperature regime (~1000F) rather than the low temperature regime (~400F). Steel is a combination of iron and carbon with other elements. However, to choose the best knife for you must consider all the properties, including toughness, edge retention, corrosion resistance, and ease of sharpening. While 14C28N and D2 are both pretty to look at, buyers always regard one over the other. The D2 version is heavier and harder, but doesn't cut as smoothly. Maxamet and Rex 121 are so extreme in terms of wear resistance and edge retention that I rated them higher than 10 because otherwise it throws off the ratings for everything else. Thanks! The Vargo Sobata 398 is unlike any other knife on this list. The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. This steel, as the name implies has a professional styling to it. So for most steels they are given a rating at around 59-62 Rc, apart from a few steels that are never used at that hardness. Hammering through hickory, digging at roots in sandy soil, and cutting around bone did nothing to chip, dent, or roll the edge of my 3V knives. However, D2 steel has better edge retention, while 14C28N offers a better sharpening experience. I also have a video that summarizes some of the information below while also showing how some of the experiments work. Still looking forward to magnacut making it into high volume production and use. The most traditional models of pocket knives have different parts, such as the handle and cutting performance. Ive found that most makers harden S30V too much, making it prone to chipping at the edge. Mid-Range Steels 154CM D2 N690 VG-10 CTS BD1N 14C28N A2 1095 O1 H1 Budget Steels 440C CTS-BD1 440A 420 8Cr13MoV AUS-8 The Steels Should you continue to scroll further, you may find yourself lost in a seemingly endless list of knife steel wealth and knowledge. 14C28N vs. D2. Only a skilled blacksmith can make Damascus steels, so they tend to be expensive. [Steel Knife Review], Best survival knife sword: 5160 steel Review, What is VG 10 pocket knife? also the angle is by far the most important factor in catra testing, so such results might be irrelevant. show very different and even inversed behaviour (e.g. Most production knives are more than thick enough at the edge to accommodate a regrind to significantly improve performance, and its a lot cheaper than buying a new knife a lot of the time. This grade can be treated cryogenically to improve edge retention. I would like to see the rating and performance on test of the Chinese Steels, that some people use to say its cheap garbage, like 3Cr13MoV, 4Cr13, 4Cr13Mo, 4Cr14MoV, 5Cr15MoV, 6Cr13MoV, 7Cr17MoV, 8Cr13MoV, 9Cr13MoVCo, 9Cr18MoV, 9Cr19MoV, and the 14cr14MovNB to see if they are similar, worse or better than the steels that they copyi believe we gonna have some good unexpected results. In fact, its not technically a steel at all, as it uses titanium and nickel. In particular, I have found the ESEE/Rowen 1095 to be less likely to chip and better at holding an edge than the KA-BAR version even in knives with the same role, thickness, and blade length. So what is the best steel for knives? And before you start arguing on behalf of the steel you think might be perfect, let me remind you that if your knife isnt perfect for a task, youll need to get another one that is! The knives can be used in humid and wet environments without rusting. Stainless steels are more resistant to corrosion but remember that stainless steels stain less, and most of them will still rust in the right conditions. Five years ago, S30V had a premium price. Give it a couple of weeks, and feedback will start pouring in. Uddeholm lists it as somewhat worse in toughness than A2 but somewhat better in wear resistance. On the other hand the professional performing blade steels sharpen to a razor edge and hold the edge for an extended use. The D2 knife blade offers high edge retention and wear resistance.
CRKT Bona Fide Review: 1.4116 Steel vs. D2 - Nothing But Knives 2. (I think the 420HC estimate in that post was based on simulation or computer modeling, since you didnt spray testing any of the 400 series.) This is also a powder-metal steel produced by American steel company Crucible. Almost all of the knives in my EDC rotation are Spydercos, in exotic steels. Typically an increase in corrosion resistance means a reduction in potential hardness for a given steel. In nitrogen steels, nitrogen is used as the iron-hardener instead of carbon, thus limiting the possibility of rusting. BD1 is excellent budget steel, very similar in composition and performance to GIN-1, a Japanese steel used a decade ago by Spyderco. Conventionally produced steels include AEB-L, A2, 52100, 12C27, 14C28N, and AUS-8/,8Cr13MoV. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) How do its properties compare to other steels? Its an update of its 12C27 and 13C26 steels, which were developed for use in shaving razors. The steel is susceptible to overheating during hardening do not overheat. Perhaps a bigger issue with the upper temper is for stainless steels, as there is a significant reduction in corrosion resistance by tempering at 1000F instead of 400F. The critical difference between these two sheets of steel is their corrosion resistance. Its a very hard steel and is exceptionally difficult to sharpen.
14c28n Steel Review - Knives & Gear AEB-L and 14C28N are the best in the high toughness group.
Different types of knife steel Alleima Yes its very easy to sharpen but it doesnt hold an edge at all. Should you continue to scroll further, you may find yourself lost in a seemingly endless list of knife steel wealth and knowledge. I wont go into detail about those here. Sign up to receive GearJunkie content direct to your inbox. The greatest living knifemaker and one of the greatest knifemakers of all time, Michael Walker, calls AEB-L one of his favorite steels. Very acute edges are more brittle but remain sharp for longer and cut very well. Theres also a line of green triangles a bit below that. Spyderco is the only production company using this steel, though Michael Gavik of Gavko knives produced a number of customs in LC 200N. Thanks Larrin, Alpha Knife Supply sells 26C3 btw. A2 knives need care taken to avoid rust and are often coated to inhibit corrosion. The biggest change that is seen with powder metallurgy in measured properties is in regards to toughness. Which one is right for you? But it doesnt have great wear resistance and thus doesnt hold an edge particularly well. If you look at the chart you may notice that at high toughness levels if you increase edge retention by only a relatively small amount you get very big drops in toughness. The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. But unlike most high-end steels, SPY27 is an easily user-serviceable powder steel. The hardness of the carbides does not matter much unlike with edge retention. This doesnt necessarily mean they have terrible toughness, but they have limitations. That is an air-hardening- high carbon, high chromium tool steel. No idea. Anthony Sculimbrene authors the blog EverydayCommentary.com. It will take you more time and energy to get a sharp edge, but your efforts will pay off because the blades hold the edge longer. 1% saltwater will separate between other stainless steels. This is especially important for chopping knives and for knives with thin edges for enhanced cutting ability and edge retention. So we get back to my original question: if a D2 planer blade at 58 Rc and the associated level of toughness will perform acceptably with a 30 sharpening angle, is there some way to extrapolate at what sharpening angle another steel with higher toughness might perform equally well? Very much appreciate you. Both of those things are no longer an issue as I now have way too many articles and a book. It should get an ultra-sharp edge for easy cutting, hold the edge for long for easy maintenance, and have a sturdy and ergonomic handle for comfort and to prevent accidents. Austenitizing is the process where the steel is heated to high temperature prior to quenching (rapid cooling) to harden the steel. The main downside is the steel is more difficult to heat treat and cant go harder than about 60 or perhaps 61 Rc. Its very hard, tough, and corrosion-resistant. rex 121 After the steel is quenched it is reheated to a lower temperature to increase toughness and decrease hardness. The knife does dull faster. [Complete Steel Guide], What is Vg-10 steel?- [Steel Knife Review], The Difference Between 440c steel vs d2: Compared guide, Is 8cr13mov Good Knife Steel [Complete Steel Guide], Amazon Best Sellers in Pocket Knives & Folding Knives. Some steels are cooked up specifically with this in mind and are very difficult to make rust. I was struggling to simplify all the Rockwell/Youngs Modulus stuff for readers when I came across your site. When it comes to handle material, both knives have options available in either plastic or metal. However, there are other factors. It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. Moreover, the blades will serve you longer because they do not wear out faster with frequent use and sharpening. I have a Winkler Knives Recon model in 5160 steel and even though the knife model is ok, the steel is shit. Each test is done with 3 or more specimens to get a good average. This makes for a great slicing knife and a perfect steel, in my opinion, for a regular-use, everyday-carry folder. what does a cvn of 40 v.s 20 mean? i understand the samples were treated in the same way. Ease of sharpening refers to how difficult it is to remove material with a sharpening stone. second it might be of importance which way you sharpened because if against the edge the steels might have reacted differently to the contamination remaining on the edge. What carbon/tool steel would you choose for a survival knife if a PM steel was too expensive? This makes it a great choice if you don't have .
How Good Is Nitro V Stainless Steel - Knives & Gear The ratings in this article rate ease of sharpening primarily based on wear resistance, but if a knife is difficult to sharpen, there may be other factors in play. Another important caveat before we get to the ratings are that these are for the steel only. Choose a factor below to start sorting. are after the ratings. it seems like all the pieces are in place to develop an algorithm for this. And easy to sharpen in our experience; and that will get an excellent razor edge that lasts for a reasonable price of time. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. Maxamets hardness results in incredible edge retention and a nightmarish sharpening and machining experience. As of November 2020, this is Spyderco-exclusive steel. Read more. Most edge retention tests isolate wear resistance or how long it takes abrasives to dull your edge in whatever youre cutting. Corrosion on knife steels most usually takes the form of rust, patina, and staining. Spyderco offers this as the high-end steel for many of its evergreen blades, like the Paramilitary 2, Paramilitary 3, Manix 2, and Native 5. I think you wrote an article a bit ago on CTS-XHP and concluded that like D2 and ZDP-189 it wasnt really stainless (although stainless is a somewhat arbitrary line). However, many kinds of wood are REALLY tough and very hard on blades. While not a powder steel, 154CM is widely used in nicer knives. With toughness it is a bit harder to link to only one article as I dont really have a summary of all of the toughness testing that we have done. The 14C28N, on the other hand, is tougher. The only thing putting me off immediately buying the p135 is the 14c28n steel. most knives are being made out of these and other mediocre steels like 14c28n, 420j2, 425m. Cool! Get for a complete guide about other steel; you can read 14c28n vs 8cr13mov reviews. Kershaw, Spyderco and Schrade are among some of the popular users of this steel.. 14C28N.
All about 14C28N Steel - HDMD Knives Blog Who looking for latest, high carbon, then the Kershaw Natrix Copper Pocketknife. and why would anyone want to use it when 420HC looks so much better for a simple stainless steel option. Why does Maxamet and Rex 121 stay the same tcc but Zmax drops and 15v goes from below 900 to over? Nitro V vs 14C28N Last but not least, 14C28N contains comparatively more vanadium elements which makes the carbides more harder and strong, which gives 14C28N a better edge retention. 14c28n steel would be a great pick thanks to its high retention and corrosion, it would be great for a normal EDC knife.
The Complete Guide to Knife and Tool Steels - Heinnie Haynes Its actually quite good, low-cost steel that performs like midprice steel. https://www.patreon.com/Knifesteelnerds, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). I think they are complementary and you should watch/read both. Steels with only vanadium carbides have the best balance of properties because the hardness of carbide matters for edge retention but doesnt for toughness. Flashlights run the gamut of price and quality. Are you looking for 14c28n steel with other steel? This is a very important factor when selecting a steel for your knife blade, especially if you plan on spending a lot of time outdoors in an area with high humidity.. S30v is a higher ranked steel and considered a true Stainless Steel, with a 14% .
Ruike Sandvik 14c28n vs D2 : r/knives - reddit While quite soft, the metal cuts even when it seems dull because, at the microscopic level, it has a roughness that performs much like a serration. Here its 8. VG-1 is a non-powder steel made by Japanese specialty steelmaker Takefu. Using 10 dps sharpening (20 degrees inclusive on the chart) leads to about 5x the edge retention of 25 dps. Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. Heres The Best Review For You (2021), D2 knife blade offers high edge retention, Dulls faster, Requires frequent sharpening. H1 Rex 45 Cold Steel still uses VG-1 on some knives, and, for the money, it does well.
In addition, According to Sandvik, 14C28N steel is easy to work on, reducing production costs and hence affordable knives. And steels with at least 10% chromium are probably stainless, except for several important exceptions like D2 and ZDP-189. Toughness is the resistance to chipping or breaking. In many cases, the D2 edge sharpness may last a bit longer. Even premium steels can have poor performance with poor heat treatment. Many steels are very similar to one another but go by different names from different manufacturers. Corrosion is not just about cosmetics and rusting, however, but can also affect edge performance. The sharpening makes the knives easy to maintain because they dull faster and require frequent sharpening. Poor availability may effectively increase cost of steel. I would also suggest adding a hardness rating to the ratings tables that currently include toughness, edge retention, and corrosion resistance ratings. Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. Its called memory metal because heat can get it to revert back to a previous shape. A2 is a tool steel renowned for toughness. 2. There are a few other complicating factors such as carbon in solution and plate martensite, especially in low alloy steels such as described in this article. This does not predict which knife will cut longer or be more resistant to chipping. D2 steel is a ordinary tool steel and knife steel. . CN Vs VG-10 The Japanese steel, VG10 offers slightly higher edge retention but has the same level of hardness as 14C28N. SUS410 The ultra high corrosion resistance steels Vanax or LC200N max out around 60-61 Rc instead. Wear resistance comes from hardness and carbides, hard particles formed between carbon and another element like Vanadium or Tungsten. Its used for combat knives, bushcrafting knives, and other applications where having a supertough blade trumps the need for edge retention and corrosion resistance. Great for tensile strength and Edge retention. Fix-It Sticks Compact Ratcheting Multi-Tool Review, Toughness, Wear Resistance, Corrosion Resistance. edge retention can vary by several orders of magnitude depending on what happens to the burr. With recommended hardness range of 55-62 HRC; the 14C28N is great for knife applications which place very high demands on edge sharpness, edge stability and corrosion resistance such as chefs knives, hunting knife, pocket knives and fishing knives. D2 knives, on the other hand, are challenging to sharpen. Honestly, yes, because its perfect steel for your knife, besides it depends on which knife, so when youre talking about chef knives, then 14c28n would be an ideal pick thanks to professional corrosion resistance and edge retention. It had better than expected corrosion resistance due to the lack of chromium carbides, a behavior also seen in MagnaCut. As a side note, pure tungsten carbide blades (from brands like Sandrin) can have very high levels of edge retention, but they are not made of steel. SPY27 To reiterate the clearer part, I wonder if toughness increases faster than edge retention decreases as an edge gets thicker. D2 steel also offers similar toughness levels as the 14c28n steel, so both aren't really prone to chipping with proper use. I see very little about cryo outside of journal articles, and I wonder which knifemakers use it. Oftentimes steels that are reported to be difficult to sharpen are in fact improperly heat treated and challenging to deburr. Most of the midrage ifferings have 14c28n, how does it compare to d2 in your experience? I know that one does not normally make knife blades of titanium, but I gather that Ti is extremely corrosion resistant, used for saltwater applications, etc. Thanks to Bill Smutz, Alex Topfer, Florian Bachler, Brunhard, Art, Rod H, Sach, Jinny Koh, Jon Duda, Cory Henderson, and UPKnife for becoming Knife Steeel Nerds Patreon supporters! But Ive found it lacking in hardness, even when compared to cheaper steels like AUS-8. Is 440A really that much better than 420HC, or have you found a narrower gap? On the other hand, 9cr18mov has a slightly higher molybdenum content which gives it higher hardness from quenching and helps drive carbide formation. Would be great if some manufactures changed their steels based on this information. Below shows a comparison of carbide structure between D2 and CPM-D2, and then toughness measurements between the conventional and PM versions of CruWear, D2, and 154CM. You cannot leave your 14C28N knives in water overnight and expect them not to rust. Spyderco has their own salt spray test setup to determine the corrosion resistance and they determined that MagnaCut is sufficiently corrosion resistant for their salt series of knives. But the true calling card of INFI is its insane toughness. Steels that can be high in edge retention and toughness are desirable for general use knives. For example, increasing edge retention from Z-Tuff to 3V (100 mm in the CATRA test) led to a drop in over 10 ft-lbs, a similar drop is seen by going from 3V to CPM-CruWear. Carbon steels are those that have primarily carbon added to them with some Mn or Si as well. YMMV Fine-carbide knife steels.
Knife Steel - BladeReviews.com I personally don`t care about stainless (sic! These steels offer a great balance of characteristics that work well, from big choppers to thin slicers. In a pocket knife the total amount of steel is rather small. Hes already done a three part series on cryogenic treatment:
Sandvik 12c27 Stainless Steel Review: Is it Really Great 14c28n | Civivi There is one exception: Bucks 420HC (Buck and onlyBuck) is produced using a proprietary heat treatment. Quite an eyeopener! https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/. Notify me of follow-up comments by email. And below shows a chart of carbide hardness, the equation we created to predict edge retention based on edge angle, hardness, and carbide volumes, and then the chart showing the good correlation: TCC (mm) = -157 + 15.8*Hardness (Rc) 17.8*EdgeAngle() + 11.2*CrC(%) + 14.6*CrVC(%) + 26.2*MC(%) + 9.5*M6C(%) + 20.9*MN(%) + 19.4*CrN(%). 2. and corrosion resistance than the 420HC steel. Below shows approximate maximum hardness vs stainless rating for several stainless knife steels. Only a few years ago Elmax was pricey, but competition has driven it down to reasonable levels, making it a decent value. Due to its higher Chromium content, S30v is a lot less likely to corrode/rust than the D2 Steel. So youre right that a D2 blade will cut more CATRA cards than an AEB-L blade *when theyre both sharpened to the same angle* but AEB-L has much better toughness and can therefore handle being sharpened to a more acute angle without chipping, and a more acute angle is more important to continuing cutting ability than wear resistance is. 440C steel at least it has some vanadium over the 420hc. It would be interesting to try to develop a conversation between /geometry/edge retention/toughness, so we could say e.g. a burr might have developped on some of the steels and not on others, it might have ben reduced or even removed by the process. Combination of knife steel properties. But if when youre searching for tough steel for your outdoor experience camping, or hunting, it would be perfect steel but not the best choice therere other steels with better than toughness that would suit your usage. This steel is quite corrosion resistant and sharpens easily. Steels that are higher in hardness and wear resistance are usually lower in toughness. Did you change the estimate based on more testing? If you are looking for a high-end knife on a budget, the varieties of both steel will serve you. The blackwashed D2 steel blade of the Kershaw Cannonball offers pretty good corrosion resistance for D2. Stainless steels are another subset of high alloy tool steels that have enough chromium in them to have stainless levels of corrosion resistance. Is it similar but worse or better at one of the 3 things? In thick forms, like a fixed blade, 1095 isa tough, low-cost steel. Read more. and get better and longer-lasting performance? Therefore, you cannot purchase the knife for use in corrosive environments. In reality hardly difference. REX 121 is a powder steel produced by Crucible. As wear resistance is increased the differences between conventional and powder metallurgy steels become greater. 420 Simple, non-stainless steels of medium carbon content like 5160 also boast high toughness. They made planer blades out D2 for its edge retention. So you can estimate how much a change in hardness would affect edge retention by following the slope of those lines.
How Is 14C28N Steel for Knives? High alloy tool steels are designed to be air hardening, so they can be cooled even slower than the oil hardening steels found above. On the other hand, these types of steel provide high wear resistance and toughness. third and most important is what happened to the burr. CPM 10V I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. Heat treatment refers to the heating and cooling steps employed to achieve your knifes proper balance of attributes. Note just because a blade is made from the premium or high-end steels listed above does not automatically mean its better than the lesser steels. In my experience, it will tarnish and discolor quickly. I can also say from personal experience that marine grade plywood will chaw up your saw blade and battery a lot quicker than standard plywood, but that probably says more about the glue that was used than the wood. Blue Super and 1.2562 have higher edge retention but relatively low toughness. Thats a pretty large difference in two budget steels that are often compared to each other.
